Hi, I'm trying to understand why my Acer Nitro5 keeps running at full power even when I don’t need much processing. The CPU stays at its maximum speed, which causes the fans to spin loudly and uses a lot of energy. When I actually want more performance, it overheats quickly and throttles down to around 2.5GHz. I used to manage this with Acer’s NitroSense settings, but they stopped working after reinstalling. Windows power options also show the CPU in a low state, yet the speed doesn’t change much under light loads. The only time it slows down is when the laptop is completely off. What might be causing this issue?
Are you running the Windows Balanced power plan? Intel processors remain stable even with many background processes. Launch Task Manager, navigate to the Details section, and review what’s active on your system. Does the Utilization graph resemble the one shown or is there excessive activity? Many users underestimate how much background software runs on their machines. Identify what keeps your CPU busy. Windows 10 performs well if configured correctly. The real inefficiency comes from unnecessary additions to your setup. Remove anything you don’t need.
I attempted to close as many background applications as I could (they tend to run continuously), but it didn’t improve the situation. In fact, it worsened performance—my CPU usage jumped from 3.9GHz to 4-4.1GHz on some cores while doing nothing. The most puzzling thing was that after changing the power management settings, HWMonitor showed improved performance; cores only increased when necessary, and I still had many background tasks. I might reinstall Windows if forced, but I’d need to replace a lot of things and hope for a better fix.
My understanding of nothing absolute centers on a complete lack of activity or data. Seeing ThrottleStop while your CPU is idle gives a clear picture—CPU usage stays under 0.5% in the idle state. Check the FIVR window for Speed Shift EPP values to see how load affects throttling. In the C States view, notice if cores remain in low-power mode constantly. Adjusting power settings can help manage performance.
I continued the tests, narrowed down more components, and remained at 4GHz with minimal CPU usage as shown by ThrottleStop (C0%<0.5, nearly all cores above C7% 98%). Then I enabled Speed Shift (default was 128) and my CPU immediately returned to its base frequency while still scaling up when required. I also experimented with setting the value to 0 or 255 to see how clock speeds changed. As expected, at 0 it stayed at full speed, and at 255 it dropped to around 900MHz when idle. I even improved over 200 points in Cinebench R23 when it reached 255 (likely due to a brief cooling period before slowing). Now I just need to figure out how to keep the EPP setting consistent after a restart (I won’t leave it at 255, it was only for testing).
